WINDMILL.

Application filed September 9, 1926.

This invention relates to improvements in Windmills and particularly to the pump rod driving mechanism thereci, and to the arrangement ot the means for controlling the operation of the mill.

One of the objects of the invention is to provide a construction and arrangement wherein the thrusts of the driving mechanism are uniformly distributed, thereby contributing to the efficient operation and durability of the device.

Another object of the invention is to provide an arrangement of the control means and "pump rod whereby interference ot these elements, one with the other, is avoided.

A further object ot the invention is to provide an arrangement wherein the actuating means of the pump rod is substantially in line With the pump rod support, thereby con-` tributing to the freedom and ease'of operation. y

A further object of the invention is to improve devices ot' this character in sundr details hereinafter described and particu arly pointed out in the appended claims.

One embodiment of the invention is shown for illustrative purposes in the accompany ing drawing, in which F ig. 1 is a plan View` of a Windmill head 1llustrating an embodimentof my invention.

Fig. 2 is a vertical sectional view taken substantially on the line 22 of Fig. 1, showing the pump rod in elevated position.

Fig. 3 is an enlarged perspective view of the pump rod drive mechanism detached from the head. y

In the illustrative embodiment shown, a :iframe inen'iber or casing 5 is provided with a horizontally extending housing 6 `forming a support :tor the bearings pi a rotatable Wind Wheel or povfer shaft T, to one end of Which ie secured a wind wheel 8 and to its opposite end a pinion 9 adapted to mesh withthe internal teeth 10 ot a rotatable member 11.

The casing 5 is preferably in the form oi a receptacle having longitudinally extending side Walls 12 and 13 and end Walls 14 and 15. The side Walls 12 and 13 are provided respectively with aligned bearings 16 and 17 adapted to receive and have secured therein by tapered pins 18 the opposite ends ot a short shaft 18 on which is rotatably mounted, between the bearings, the rotatable member 11. Formed, preferably on the Wall 15, are a pair of upstanding bearinglugs 19 1having aligned openings adapted to receive a shaft 20 on the outer ends of which is mounted one end ot an oscillatinvr or rocker arm 21, While with an eccentric disc 23 adapted to receive an eccentric strap 24havinv an arm or pitman 25 formed thereon, the saidnarm or pitmanextending` outwardly from the disc and having its outer end adapted to engage an aperture in the oscillating arm 21 and to be pivotally connected to said arm by means Ot a short shaft 26. y i

It will beobservcd from the foregoing description that the shaft 18 is suitably supported at its Vopposite ends, thereby providing a most cflicientfand practical mounting for the rotatable member 11p, and that the thrust of the eccentric disc and its connections With the reciprocating pump rod 22 is iii-substantial alignment with the plane of movement of the oscillating arm `21, thereby reducing to a minimum any cramping action of the pump rod drivingmechanism.

The casing 5 is provided, preferably` adjacent the side Wall 13,`with a vertically extending sleeve portion 27"having an enlarged central bore 28 adapted to receive the upper end ofthe tubular mast 29. By reference to Fig. `1 it will be noted that the pump rod extends downwardly through the f bore and mast at onf-: side of the center thereof and that a she-ave il() mounted in the upper end of the bore 2S. A chain 81 4for controlling` the operation ol the, mill extends upwardly through the mast and is trained over the sheave 30 and around a second sheave 32 and at its end portion is connected tothe Wind vane 33 in a manner to manipulate the vane for permitting the Wind Wheel to rotate and actuate the pump `rod or to secure the wheel against rotation. This Wheel controlling mechanism maybe ofany suitable design, such as shown, lfor example, in Fig. 1, in which an upstanding lug 34 on the vane 33 is adapted to engage one end oa rocker arm 35, the opposite end oi' which is connected by means of a cross rod 36 with a bell crank lever 37 adapted to actuate suitable friction brake mechanism (not shown) wit-hthe hub of the vrind Wheel 8. y I i It Will be observedthat in the arrangement of the control chain and pump rod that the vertical run of the chain occupies a position to one side of the rod and transversely to the plane of movement of the oscillating arm 2l for actuating the rod, thereby avoiding any interference of the rod and chain by reason oi. any lateral movement of the rod due to its connection with the oscillatingl arm 2l.

For suitably oiling- `the connections of the pump rod drivingl mechanism, the casing 5 provides a receptacle or sump tor containing` a supply of oil SS adapted to be carried upvvardly by lins 39 formed on the rotatable member ll, and, i the iins reach their uppermost position, to deposit the oil by grav ity on the upper side oil the eccentric and the arm 2l. To facilitate the distribution oi the oil to the various connections, the arm 2l is provided adjacent its edges with upstandingl flanges 40 adapted to retain the oil on the upper side of the arm to insure its transmission to oil openings formed in the bearing portions of the arm at its connections with the shaft 2O and its pivotal connection with the pump rod 22. For conveying the oil deposited by the iins 39 to the top of the arm, the arm 2l is provided with aV plurality of laterally disposed channels ll extending` beneath the fins, as clearly shown in Fig. l, While a channel Ll2 positioned preterabiy between the channels 4l provides for the tansmission of oil to the pivotal connection of the arm or pitman 25 with the oscillating arm.

It Will be observed from the foregoing description that the present invention provides a construction and arrangement wherein the connections of the pump rod driving mechanism are in substantial alignment and Wherein the thrusts of said mechanism are uniformly distributed, thereby contributing to the ei'iicient operation and durability of the device,v and wherein any interference between the pump rod and the control means is avoided.

lt will be observed further that the present invention provides eilicient oilingg means t'or all of the connections ot' the driving` mechanism, thereby reducing to the minimum the Wear of the various elements at these points.

Obviously, the presentinvention is not limited to the precise construction and an rangement shown and described but may be variously modified without departing` from the spirit and scope of the invention as set forth in the claims. Moreover, all the features of the invention need not be used conjointly, as the same may be used to advantage in variously diierent'combinations and subcombinations.
